Glad to hear about your simple WX station project!
My opinion is: Send WX and POSITION in a single
packet (using "complete WX format"). Then send
anything else in a "STATUS" packet just as you
If there are clients that do not display the status packet
then that is a client display issue, and not a protocol
The advantage of the above technique, is that you
have 98% freedom in what you put in the packet
(as long as it starts with a ">")...
But if you dont mind being constrained to the 5 channel
Telemetry format, you can also then send analog telemetry
using the APRS telemetry format (which the KPC-3 has
implemented)... but then you have to also tell people
what the 5 channels are and what they mean...
Original message continued:
I'm still working on 1-wire support for the OpenTracker, and at the
I've got freeform text plus battery voltage and board temperature
in a separate status packet every n transmissions. The only problem
this is that neither FindU nor aprsworld seem to report status text in
weather views. Xastir shows both, albeit in its usual hard-to-read
UI-View32 displays it just fine.
I think the whole setup should be a contender for the lowest-power
weather station. The 3" square test board has integrated radio power
control, so average power consumption depends a lot on how much the
on. With an upgraded regulator and power save mode enabled,
idle should be under 5 ma at 12 volts - should work quite well on a
solar panel. The test station is N1VG-4 if you want to check it out.
might bring it along to DCC if anyone's interested.
